具體壓縮、解壓代碼實(shí)現(xiàn)參照網(wǎng)絡(luò)上的代碼，貼出概要代碼：
復(fù)制代碼 代碼如下:
/// <summary>
/// 壓縮文件
/// </summary>
/// <param name="sourceFilePath">源文件路徑</param>
/// <param name="destinationPath">壓縮文件后的保存路徑</param>
/// <returns>壓縮是否成功</returns>
public bool Compress(string sourceFilePath, string destinationPath)
{
try
{
string[] filenames = Directory.GetFiles(sourceFilePath);
using (ZipOutputStream zs = new ZipOutputStream(File.Create(destinationPath)))
{
zs.SetLevel(9);
byte[] buffer = new byte[4096];
foreach (string file in filenames)
{
ZipEntry entry = new ZipEntry(Path.GetFileName(file));
entry.DateTime = DateTime.Now;
zs.PutNextEntry(entry);
using (FileStream fs = File.OpenRead(file))
{
int sourceBytes;
do
{
sourceBytes = fs.Read(buffer, 0, buffer.Length);
zs.Write(buffer, 0, sourceBytes);
}
while (sourceBytes > 0);
}
}
zs.Finish();
zs.Flush();
zs.Close();
}
}
catch (Exception)
{
return false;
}
return true;
} public bool DeCompress(string sourceFilePath, string destinationPath)
{
try
{
using (ZipInputStream zs = new ZipInputStream(File.OpenRead(sourceFilePath)))
{
ZipEntry entry = null;
//解壓縮*.rar文件運(yùn)行至此處出錯(cuò)：Wrong Local header signature: 0x21726152，解壓*.zip文件不出錯(cuò)
while ((entry = zs.GetNextEntry()) != null)
{
string directoryName = Path.GetDirectoryName(entry.Name);
string fileName = Path.GetFileName(entry.Name);
if (!string.IsNullOrEmpty(fileName))
{
using (FileStream streamWriter = File.Create(destinationPath + entry.Name))
{
int size = 2048;
byte[] data = new byte[size];
while (true)
{
size = zs.Read(data, 0, data.Length);
if (size > 0)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}
}
}
}
}
}
catch (System.Exception)
{
return false;
}
return true;
}
如果需解壓*.rar的壓縮文件在網(wǎng)絡(luò)也可以找到相關(guān)的實(shí)現(xiàn)代碼，概要代碼：
復(fù)制代碼 代碼如下:
public bool DeCompressRAR(string sourceFilePath, string destinationPath)
{
try
{
string SeverDir = @"D:/Program Files/WinRAR";//rar.exe的要目錄
Process ProcessDecompression = new Process();
ProcessDecompression.StartInfo.FileName = SeverDir + "http://rar.exe";
Directory.CreateDirectory(sourceFilePath);
ProcessDecompression.StartInfo.Arguments = " X " + sourceFilePath + " " + destinationPath;
ProcessDecompression.Start();
while (!ProcessDecompression.HasExited)
{
//nothing to do here.
}
return true;
}
catch (System.Exception)
{
return false;
}
}
我本想利用FileUpload控件將上傳的壓縮文件解壓后保存至相對(duì)應(yīng)的目錄并更新數(shù)據(jù)庫(kù)文件目錄，后發(fā)現(xiàn)一些較好的用于上傳的開(kāi)源軟件：如NeatUpload，SWFUpload可以較方便的實(shí)現(xiàn)我的需求，遂沒(méi)有過(guò)多糾纏于SharpZipLib,可能關(guān)于SharpZipLib的壓縮與解壓有其它用法，不能被我誤導(dǎo)，以上代碼是從網(wǎng)絡(luò)上整合出來(lái)的，因?yàn)樗^(guò)于重復(fù)和散亂。
AspNet技術(shù)：asp.net SharpZipLib的壓縮與解壓?jiǎn)栴}，轉(zhuǎn)載需保留來(lái)源！
